I'm new to the Gardening Forum but have raised garden plants my entire life. I have recently (last year) begun to grow thornfree blackberry plants. This year they are growing
profusely with large canes from last year fully loaded with berries. I have four different varieties of blackberry plants: Quachita, Apache, Triple-Crown and Black Satin. My question is this: Which of the thornfree blackberries is the sweetest tasting? I know for certain the Black Satin is rather tart, needing a little sugar to make them more edible. But which thornfree blackberry is the sweetest tasting off the vine without having to add sugar?
